INDEX.

Application led September 27, 1920. Serial N'o. 413,085.

To all whom t man] concern:

Be it known that I, JOHN T. QUIGLEY, a citizen of the United States, anda resident of Boston, in the county of Suffolk and State ofMassachusetts, have invented an Improvement in Indexes, of which thefollowing description, in connection with the accompanying drawings, isa specification, like characters on the drawings representing likeparts.

This invention relates to paper files and is more particularly concernedwith indexes. The invention will be best understood by reference to thefollowing description when taken in connection with the accompanyingdrawings of one illustrative embodiment thereof, while its scope will bemore particularly pointed out in the appended claims.

In the drawings:l

Figure 1 is a front elevation of a self-indexing file exemplifying myinvention;

Fig. 2 is a sectional view on an enlarged scale on line 2-2 of Fig. 1;

Fig. 3 is a sectional view also on an enlarged scale on line 3-3 of Fig. 1;

Fig. L is a front elevation of a sheet prepared for the making of thefiling elements by severing the sheet along certain predetermined linesand then folding the resulting pieces along other predetermined lines;and

Fig. 5 is an end elevation of one of the filing elements on an enlargedscale as it appears before being placed in the holder.

Referring to the drawings and to the embodiment of my invention which isselected for exempliication, I have shown a file comprising a series offiling elements in the form of record slips 10 abutting edge to edge andheld in a suitable holder, herein a frame Comprising a pair of channelmembers 12 provided with inwardly facing flanges 14 presenting channels16 in which the terminal portions of the filing' elements are received.The ends of the channel members are appropriately secured to suitabletie pieces 18. In the present example I have shown a double faced panel,that is to say, one presenting two sets of oppositely facing filingelements and 'in order to prevent interference of one set with the otherI have provided an intermediate wall 2O (see Fig. 3).

Referring now to the filing elements, eac-h is formed of a. sheet ofpaper folded to present an accordion-like, bendable, compressible andresiliently expansible bar, whose construction is such that it may bebent to allow it to be sprung into or out of the holder, compressed inits cross-section for introduction into the channels and having inherentexpansibility whereby it is frictionally held against accidentaldisplacement in the holder. This is most conveniently acco-mplished byfolding the sheet to present a plurality of acute-angled, resliently`expansible bends,vherein two folds 22 and two folds 24. In other words,the sheet is folded-to present a record tablet 26, a pair of oppositelyand inwardlyrinclined arms 28 and a pair of oppositely and outwardlyinclined arms 30 (see Fig. f

The described folds have a tendency to open, that is to say, the anglesincluded between the sides of the folds tend to become less acute, theresult being that the 'crosssection of the bar is resiliently expansiblein a direction perpendicular to the face of the writing tablet 26 and bysimply making the channels 16 a proper depth from front to back theindex elements are frictionally held against accidental displacement.Moreover since the cross-section is symmetrical there'is avsubstantialequalization ofv pressure at both longitudinal edges of the bar and whenlthe edges of the two folds 24 are brought together, as they appear inFigure i 2,v the arms have a sort of bracing effect. Another importantfeature of my invention is that owing to the compressible nature of thebars the faceof' any bar may be pressed inward by the application of thefinger thereagainst thus reducing its depth from front to back to asuiiicient extent to enable Ithe next adjacent har to be drawn forwardby the finger nail and bent to withdraw its ends from the channels.

The preferred method of making the liling elements is to provide a sheet32 (see Fig. 4) whose width is the same as the length of each finishedfiling element, the length of the sheet being such as to permit one ormore and preferably several filing elements to be formed therefrom. Asan aid in severing the sheet and folding each of its parts to form thefiling elements I provide the sheet with a plurality of groups of scoredlines, each group comprising a pair of generally parallel lines A-Abounding what is to be the writing tablet, a pair of parallel `linesC-'C Which are to form the free ends of the arms (see F ig. 5). Inthepresent. veXample-there-is left atone end of-.thesheet a narrow strip34 Which it is intendedto tear off and discard.V Also in the presentexample the scored line C-C of one group is identical With such line ofthe next succeeding group, thatis toV say, it is .commonito the adjacentgroups. The best results are secured by making the scoringsdiscontinuouslike a series ofzdashes-(fsee Fig. 4). This isk preferredvbecause there is left between the dashesan unscored portion Where Y thefibers of the paper are vunweakened and vtherefore furnishfthe necessarystrength and resiliency vfor the hinge which they constitute at the`bend in the -fiinis'hedI tilingelement.

The-first stepuisto Write the'names-and address or otheridatalon theWriting'ta'blets,

` then'sever along .the severallinesG-C and finally fold the Aresultingpiecesalong their support lines'as represented inFig. 5.
